The Schedule referred to in these Letters Patent anni makng'part of the same.

To all to whom 'it may concern:

Be it known that I, J oHN WEBSTER, of College street, Chelsea, in the county of Middlesex, England, have invented an Improvement in the Means of Preventing Incrustation in Steam-Boilers and other Vessels; and I do hereby declare that vthe following is a full and exact description thereof, reference being had to the accompanying sheet of drawings, and to the letters of reference marked thereon.

Figure 1 represents a side elevation of the boiler of alocomotive-engine, showing this invention adapted thereto. l v

Figure2, a top plan view rof'ig. 1

Figure 3, a detached View of o'ne of the parts hereafter referred to.

The nature of this invention consists in bringing into contact with the water of a boiler'or other vessel, by devices hereinafter set forth, a surface of fibrous material, such as tow, hemp, flax, jute, (pulped, or otherwise,) or other suitable substance for collecting the incrustatingmatters of the water, and removing the said fibrous material, or other substance, when charged with incrustating-matter, without derangement of the-boiler, or other vessel, while generating steam, or not.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construc-` tion and operation.

A. A mark the body of the boiler.

B, the smoke-box.

O, steam-chamber.

I), fire-box.

E, a tube, connected,` by short pipes G, to the boiler, at the bottom thereof, and also near the top of the boiler, at about the level of the Water therein, for the purpose of insuring circulation of the water in the boiler through the tube E.

The pipes G are fitted with cocks, H, and the tube Eis fitted with a screw-cap, a, at its upper end, for closing the end of the tube after the perforated pipe I, shown at iig. 3, has been inserted in the tube E.

The p ipeIis filled loosely with anycheapand suit able fibrous material-tow or hemp, for example; and, when so filled, in order to place it within the tube E, which can be done' while the boiler is at work, the cooks H must be shut oii, to prevent the escape ofthe water. The cap a is then screwed on, and the cocks H opened, thus allowing the Water in 7the boiler'to pass through the fibrous material in the pipe I, -by which the earthy and extraneous matters contained in the water will be arrested by the fibrous material during the circulation of the water through the tube E, and thus prevent the incrustation of the inside of the boiler which usually takes piace.

When the brous material is sufciently charged with earthy matter, the pipe I, containing it, is removed, the cocks H being first closed. Fresh fibre is then placed in the pipe I, and the pipe replaced iu the tube E, and so on, from time to time; and this principle of collecting the earthy matter contained in the water of boilers and other vessels is intended to be applied to all kinds of boilers, the mode of applying such principle depending upon the situation and shape of the boiler or other vessel, the object of this invention being to prevent incrustation in boilers and. other vessels.

K is a small cock, for discharging water and steam from the tube E, before withdrawing the pipe I there- Witnesses: v
